Basic Mechanical Properties of Basalt Fiber Reinforced Recycled Aggregate Concrete

Table 1: Performance indexes of materials.

Cement			Recycled coarse aggregate				River sand			Fly ash
Grand	Density (g/cm³)	f_cc (MPa)	Size (mm)	d_ac (g/cm³)	d_ap (g/cm³)	ω	d_ac (g/cm³)	d_ap (g/cm³)	Fineness modulus	d_ap (g/cm³)	Fineness level
P.O 42.5	3	49.6	5-20	1.4	2.6	3.8%	1.6	2.7	2.46	2.2	Second

Note: f_cc means compressive strength of cement at 28 days; d_ac refers to stacking density; d_ap refers to apparent density; ω refers to water absorption content.
